但是，uname 的输出是
bwvdnbro@wixie:~$ uname -a
Linux wixie 3.16.0-30-generic #40~14.04.1-Ubuntu SMP Thu Jan 15 17:43:14 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux
据我所知，这个内核没有安装。这怎么可能？我刚刚重启了电脑，所以当前运行的内核应该是最后安装的内核。
答案1
如果你没有手动安装它，那么它的包名称是linux-image*。也就是说你在列表中看不到它dpkg -l | grep linux-image。
/boot检查文件夹中所有内核确实存在ls -l /boot/使用检查其包
dpkg -S /boot/<kernel-filename>
有其他相同版本的内核包，请参阅packages.ubuntu.com
